What Is Food Processing? Food processing is the set of methods and techniques used to transform raw ingredients into food or to transform food into other forms for consumption. It encompasses everything from cleaning, grading, sorting, cooking, and freezing, to labeling and packaging. While some people view food processing as a necessary evil – something […]
